A Convenient Conversion of Terminal Alkenes into Homologous Unsaturated and Doubly Unsaturated Esters

Abstract

Unsaturated and doubly unsaturated esters have been synthesized in two steps by the application of a radical xanthate transfer process of a simple methylsulfoxide starting material to a range of terminal alkenes. <i>syn</i>-Elimination of the sulfoxide gives α,β-unsaturated esters, which coupled with a xanthate elimination yields α,β,γ,δ-unsaturated esters
